Otala lactea

Otala lactea, known as the milk snail or Spanish snail, is a large, edible[2] species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk, in the family Helicidae, the typical snails. Archaeological recovery at the Ancient Roman site of Volubilis, in Morocco, illustrates prehistoric exploitation of O. lactea by humans.[3]

Anatomy
love dart of Otala lactea.

This snail creates and uses love darts as part of its courtship behaviour, prior to mating. The shell of the snail plays an important role on its quality of life. This is because the calcium in the snails shell allows for shell regeneration to take place, if the shell was ever to be broken.[4]
